While London was toasting Queen Elizabeth II at her Diamond Jubilee, Washington celebrated as well. On June 2, Princess Selene Obolensky welcomed friends and four generations of the honoree’s family to toast Countess Gertrude d’Amecourt, who at 102 years continues to exude her well-known charm. The elegant doyenne was serenaded at the piano by John Gardecki and surrounded by admirers.
